brians7 Posted November 19, 2009 Share Posted November 19, 2009 Great information here. I am going to try and build a pair of CornScala's myself. Personally I like the slimmer profile, and was going to build a pair with the basebin dimensions being 21.5 wide, 21.5 deep, and 28 high, this should give the interior volume 6.2 cu. ft. Now for the port shelf, if I am understanding this correctly the port needs a cross-sectional area of between 70 and 75 cu in. and if the interior width of the cabinet is 20 in. and I make the support board for the shelf the enitre height of the port that makes the width of the port 18.5 inches wide, and if the port is 4 in high 4x18.5 is 74 cu. in. The port shelf length remains 9.5 in. I hope that these calculations aren't wrong in any way, because I plan on starting this project really soon. And if the they ARE wrong that someone will chime in and revise them for me. A bit more insight about the speakers, they will be split top design. I will be using Crites Speakers CW1526C Cast Frame Woofers, Altecs 811 horns which I already have, Great Plains Audio 902, and JBL 2404H baby cheeks which I also already have, ALK Engineering crossovers. Thanks. Brian. Quote Link to comment Share on other sites More sharing options...

rogerwilco82 Posted November 20, 2009 Share Posted November 20, 2009 Hi Brian, this is my construction for a "slimmer" CornScala. Dimensions are 20.5" W x 43.3" H x 23.6" D. I'm using K-401 Horns with Atlas drivers. I will post more pictures when they are completed. Robert Quote Link to comment Share on other sites More sharing options...
brians7 Posted November 23, 2009 Author Share Posted November 23, 2009 Thanks for the response. Robert how did you come up with your port dimension. WinISD shows the port should be 18.5x3.25x9.75 with the cabnet tuned to 38Hz. Now in this thread (http://forums.klipsch.com/forums/p/81721/816459.aspx#816459) it says that the port should have a cross-sectional area of 75.205in^2 and the motor bord should have a across-sectional area of 50.00 in^2. giving me a port 18.5x4.0x9.25 and 3 openings in the motor bord 5.0x3.33. I wonder which is right ? thanks Brian Quote Link to comment Share on other sites More sharing options...
rogerwilco82 Posted November 24, 2009 Share Posted November 24, 2009 Hi Brian, I got the port dimensions from the cornwall III port and Bob Crites. Robert Quote Link to comment Share on other sites More sharing options...
fidget Posted April 17, 2010 Share Posted April 17, 2010 I know this is an old post. But does anyone know if these measurements work. Thanks Quote Link to comment Share on other sites More sharing options...

rogerwilco82 Posted February 2, 2011 Share Posted February 2, 2011 The internal volume of the bass bin correspondents with the Cornwall III - so YES. Quote Link to comment Share on other sites More sharing options...
Lasset Posted February 22, 2011 Share Posted February 22, 2011 Hi Robert, how deep did you make the port? Mvh Lasse. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted January 22, 2013 Share Posted January 22, 2013 rogerwilco82, Wow. that speaker would have to sound awesome. Notice that you have a pic of these cabs as your avatar. Do you have any other pics of your project you might post? I think you have nailed cornscala in a tower orientation. would love to hear them.
